/*
 * Settings panel (redesign 2026-11).
 *
 * A side rail with the four sections (Audio, Plugins, MIDI / Drums,
 * Shortcuts) and, on the right, the open section. Audio is split into
 * groups in the order a musician sets things up: Devices, Engine,
 * Metronome, then Diagnostics folded away. Every control, id and handler
 * is the same as before; only the order and the look change. The panel
 * keeps its fixed position and viewport insets from styles.css.
 * Phones (up to 760 px) keep the tabs on one row above the section.
 *
 * Up to 1024 px the footer box that holds the panel is hidden, so Settings
 * opened from the menu used to stay invisible. While it is open the box
 * now takes no space and shows nothing but the (fixed) panel.
